WebThe probability density function for the Rayleigh distribution is. P ( x; s c a l e) = x s c a l e 2 e − x 2 2 ⋅ s c a l e 2. The Rayleigh distribution would arise, for example, if the East and North components of the wind velocity had identical zero-mean Gaussian distributions. Then the wind speed would have a Rayleigh distribution. WebMay 18, 2014 · $\begingroup$ Unfortunately, there are several incorrect statements in this …
